5 terms

greenhouse gas emissions intensity technical

"achieve a 25% reduction in greenhouse gas (GHG) emissions intensity by 2029"

Greenhouse gas emissions intensity measures how much greenhouse gas a company or activity produces for each unit of output—commonly per dollar of revenue, per product made, or per unit of energy used—so it shows pollution relative to scale rather than total emissions. Investors use it like a “miles per gallon” gauge for carbon efficiency to compare peers, judge regulatory or carbon‑pricing exposure, and assess whether operations are becoming cleaner or riskier over time.

available lower berth days technical

"measured on an available lower berth days basis compared to its 2019 baseline"

The total count of days during a reporting period that lower berths (sleeping beds in cabins or carriages) were available for sale or occupancy across a fleet or property. Investors use it as a capacity measure—like counting how many hotel beds are ready each night—to compare against actual nights sold to calculate occupancy and revenue potential for companies in travel, shipping, or passenger rail businesses.

shore power technical

"expanded shore power capabilities that allow ships to connect to local electrical grids"

Shore power is the practice of plugging ships, ferries or other vessels into an onshore electrical supply while docked so they can turn off their engines and onboard generators. Like plugging an electric car into a charger instead of idling the engine, it reduces fuel use and pollution and can lower operating costs, affect compliance with environmental rules, and create demand for port electrical infrastructure and related investments.

air lubrication systems technical

"waste heat recovery systems and Air Lubrication Systems that help ships move more efficiently"

A system fitted to a ship's hull that pumps a layer of air or fine bubbles along the bottom to reduce friction between the hull and the water, like sliding on a thin cushion of air. It matters to investors because it can lower fuel use, emissions and operating costs for vessels, affecting shipping companies' profitability and regulatory compliance with emissions rules.

battery energy storage technical

"peak energy use shaving with battery storage systems"

A system that stores electrical energy in rechargeable batteries so power can be used later, like a large-scale rechargeable power bank for homes, businesses, or the electricity grid. It matters to investors because it helps smooth out supply and demand, lets operators sell power when prices are higher, backs up critical services during outages, and supports more renewable generation — all of which can create new revenue streams and reduce operational risk.

World's largest cruise company reinforces GHG intensity goal with new 25% reduction target by 2029, raising previous goal by five percentage points and accelerating timeline by one year

New target follows company achieving original 2030 goal five years early thanks to its comprehensive decarbonization strategy

MIAMI, Aug. 6, 2026 /PRNewswire/ -- Carnival Corporation (NYSE: CCL), the world's largest cruise company, announced a new sustainability target to achieve a 25% reduction in greenhouse gas (GHG) emissions intensity by 2029, measured on an available lower berth days basis compared to its 2019 baseline. After successfully reaching its 2030 goal five years ahead of schedule – cutting GHG emissions intensity by 20% in 2025 – the company raised its original target an ambitious five percentage points and accelerated its timeline to achieve the goal a full year early in 2029. The efficiency work behind that milestone is also showing up on the bottom line with fuel-efficiency gains on track to save the company roughly $650 million in 2026 alone versus 2019 levels.

Carnival Corporation's progress, detailed in its newly published 2025 Sustainability Report, is driven by a comprehensive decarbonization strategy focused on operational improvements, energy efficiency investments and low-GHG power generation. Together, these efforts have delivered sustained emissions reductions over nearly two decades. Since 2008, the company has reduced its GHG emissions intensity by 44%, meaning emissions associated with each guest sailing have been cut roughly in half during that period.

"Achieving our 2030 GHG reduction goal five years early is a significant milestone that reflects years of disciplined investment, innovation and operational focus across our global fleet," said Josh Weinstein, CEO of Carnival Corporation. "But we're not treating it as a finish line. Our new 2029 target ensures we're continuing to improve every part of the equation, from using less fuel to advancing the tools, technologies and infrastructure that will help us lower emissions even further over time. That's good for the planet, good for our business and gives us real confidence in the road ahead."

To achieve its 2029 target, Carnival Corporation's decarbonization strategy prioritizes lowering energy use today while developing the flexibility to pursue multiple fuel pathways in the future:

Operational Improvements & Energy Efficiency Investments
One way Carnival Corporation reduces its GHG emissions intensity is by continuously improving ship operations and adopting technologies that lower energy use across its fleet. Together, these efforts help reduce fuel consumption, drive performance and support the company's ongoing emissions reduction goals, while maintaining the award-winning guest experiences its cruise lines are known for.

Operational enhancements, including smart itinerary planning and voyage optimization tools, help identify the most fuel-efficient routes and sailing patterns. Carnival Corporation is also integrating technologies that reduce energy demand, improve hydrodynamic performance and capture energy that would otherwise be wasted. These efforts range from Power Saver Packs that reduce HVAC and lighting loads to waste heat recovery systems and Air Lubrication Systems that help ships move more efficiently through the water. Complementing these initiatives, seven new ships scheduled to join the fleet through 2033 are expected to deliver more than 20% greater efficiency per passenger than current ships.

Low-GHG Power Generation
At the same time, Carnival Corporation is investing in a range of low-GHG technologies and solutions, recognizing that no single approach alone will deliver net-zero ship operations. This includes a growing fleet of LNG-powered ships, expanded shore power capabilities that allow ships to connect to local electrical grids while in port, increased biofuel use as more supply comes online and peak energy use shaving with battery storage systems. Together, these investments are advancing lower-emission operations today while building flexibility to adopt future energy solutions as they mature.

Carnival Corporation's decarbonization strategy is a cornerstone of its climate action efforts and is one of its many planet-focused initiatives, which also include programs to advance a circular economy model, support biodiversity and conservation, and promote sustainable tourism.
